Chest Pain And Burning Sensation, Dry Cough, Running Nose, Fever. Taken Azithromycin And Paracetamol. Medication?

Dear Sir, I am suffering from dry cough with the chest burning and pain since three to 4 days. But the cough was started before three weeks with the slight fever and common cold. At that time I used the medication azitheromycin and paracetamol for three days. After that I cured from the running nose and fever. But one day The weather was suddenly changed (winter to spring in Korea), The cough was increased drastic. Then I consulted the doctor. He given some prescription for six days with the Mantekluk fast tablets. After that, I used to lying down on the bed after the full meal and taking citrus food and coffees often. To day Morning I took the tablet Pantaprazole capsule.
Sir, still I am suffering from the dry cough and burning in the chest with little pain. Sir, please suggest the medication and how to prevent this disease. I am looking forward for your answer.
